Firewall & Security Appliances

Today's networks increasingly face security threats that must be addressed. A number of different electrical devices, among them firewall and security appliances, must communicate with each other reliably and efficiently to ensure the integrity, safety and normal performance of the network. Inside a typical enterprise networking system, both wired and wireless security appliances play a critical role in ensuring reliable, energy-efficient and cost-effective operation of the entire network. Fairchild provides solutions that deliver the higher performance and reliability, greater energy efficiency, and lower total cost of ownership that are required of today's security and firewall devices.

Design Advantages

  • TinyBuck® POL regulators with integrated PWM controller, driver and MOSFETs optimize performance and energy savings
  • Lower the total solution cost with an integrated 700V internal switch
  • Ultra-low standby power minimizes the converter power loss during idle
  • Extensive portfolio for various AC-DC and DC-DC applications
  • Design circuits are simplified with high voltage start-up circuit internal
  • Input Under-Voltage Lockout (UVLO) / Output Over-Voltage Protection (OVP)
  • Excellent efficiency in a small form factor
  • High-voltage SuperFET® II super-junction MOSFETs provide robust body diode performance for designs requiring high power density, system efficiency and reliability
  • Extensive portfolio of board level analog and mixed signal ICs offers extensive signal path expertise with a particular focus on USB, audio, video and signal routing application, providing innovative detection and routing capabilities
